Passive cooling (no machinery to move coolant) for new-generation avionics is an attractive approach that can produce overall improvements in airplane reliability and reduced costs of operation. Active cooling systems (using machinery to move cooling air) impose airplane penalties in terms of weight, volume occupied by machinery, cost, complexity, reliability, and performance. Tests and analyses demonstrate that passive cooling can produce avionic equipment internal temperatures equivalent to active cooling if thermal design techniques are employed early in the design process of the boxes.
